ITHACA, N.Y. -- It's a fast paced, hart hitting sport.

"In each jam, you have four blockers and two jammers," explained skater Dr. Jennifer "The Harlot Pimpernel" Biermann. "The blockers start moving on the first whistle and there will be a second whistle after that when the jammers go. The jammers have to move through the blockers and lap them. And on their second pass through they get a point for each blocker they pass on the opposite team."

The recent revival is taking the country by storm. And the competition just got smaller.

"It just feels fun to be with all my friends and having fun at the same time. And just doing something that I love," said nine-year-old Pearl "Racing Rainbow."

"It's lots of fun and really hard, though, because it's really hard to skate when there's lots of people staring at you," said 11-year-old Indigo "Indy-structible."

The Ithaca League of Women Rollers started the first junior derby league in New York State as a service to the community, teaching girls as young as eight the tricks of the track.

"I'm surprised by their skating skills, actually. Some of them are much better skaters than I am," said Biermann, who coaches the junior rollers. "I think it's that they have no fear."

They may look like a bunch of cute little girls, but there's nothing little or girly about the way they play derby.

"It's like a bunch of strategy. So you have to think about everything that you do," said 11-year-old Kaitlyn "KandyKate."

"You get in front of them and try to block them with your butt," Indigo said. "But it's actually really hard because if you don't have a partner next to you, it's kind of hard because they can just get around you."

And though these tiny wheeling terrors don't hit like their grown-up counterparts do...

"No. There's no intentional hurting. Only accidentally," Pearl said.

Their coaches say the sport has toughened them up.

"They're getting a lot of exercise. They're becoming more confident," Biermann said

And when the last whistle blows...

"Well it's not basically about winning, it's about having fun," Pearl said. "It's really, really fun."

And learning what to do when you get knocked down.

"I get back up and try to go as fast as I can," Indigo said.

The junior rollers are making their debut Saturday at half-time, when Ithaca's SufferJets take on the Wall Street Traitors from New York City in Cass Park.
